Fig. 2. The correlation of interphase telomere length (TL), metaphase TL, and age. (A) The linear regression model for age and interphase TL. (B) The linear regression model for age and metaphase p arm and q arm TLs. (C) The correlation between interphase TL and metaphase TL. The correlation coefficient for interphase TL and metaphase p arm TL is −0.498, P=0.013 and for interphase TL and metaphase q arm TL, −0.445, P=0.029. TL plotted is the telomere/centromere fluorescence intensity ratio.
